The agency said Wheatcroft wasn't following officers' commands and that Wheatcroft's wife hit an officer in the head with a plastic bag containing full soda cans, knocking the officer to the ground.

During the briefing with reporters, spokespeople for the police department declined to answer several questions, such as whether it was within agency policy to use a stun gun on a person who was handcuffed.

Police say Wheatcroft and his family were passengers in a car that was suspected of a traffic violation.

Agency spokesman Sgt. John Roth said the kick to Wheatcroft was allowed under a policy regarding people who are resisting officers.
